Well? Who do you rate higher in a ATG List and who do you feel was a better fighter in terms of legacy?
Roy. 4 division champ. One of only two fighters to go from Middleweight to Heavyweight and win a title. Fromer P4P #1 from 1993 to 2004. Dempsey sat on his title for awhile after making three defenses before losing to Gene Tunney. He's not even a top 10 Heavyweight.
Basically I think he is the better fighter in almost every aspect and I think he had the better career, though in that regard its a lot closer.
Jones by miles and miles and miles and miles... ...in terms of ATG lists. Obviously they are both wonderful fightes. But when I did 100, Dempsey was nowhere near and Jones was top 30.
